Happy birthday to #astronomer Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & evolution of our universe! The Nobel committee waited 3 years after she died to reward another for the theory of dark matter. 🧵1/ https://minouette.etsy.com/listing/1393796836 #printmaking #sciart #linocut #mastoArt

Happy birthday to #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. My portrait of Leavitt is printed in silvery lavender ink on Japanese kozo paper. Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, Ursa Minor & Andromeda). ⁠🧵1/ ⁠ #linocut #printmaking #WomenInSTEM #sciart #histsci #astronomy #mastoArt

Our next partner is very special because Space Place Planetarium Canada is a non-profit charitable organization of professionals from many backgrounds, including public infrastructure, government, museum and business, who were drawn together by the dream of bringing an iconic planetarium back to Toronto. We can’t wait for your impact this year!

Day 11 #ArtAdventCalendar: Happy birthday to trailblazing US #astronomer Annie Jump Cannon (1863 – 1941), here with her stellar classification system which sorted stars based on spectral types, revealing their temperature from hot blue to cool red stars: O,B,A, F, G, K & M. Named the Harvard Classification after the university, her tremendous contribution was less visible. 🧵 #printmaking #womenInSTEM #histsci #DisabledInSTEM #linocut #mastoArt
